Just for those who are interested in generating HTML with Guile: Some
time ago, I wrote a little skript for generating my personal pages,
which is small, simple to use and closer to writing HTML (for example,
you can use Emacs' html-mode without great problems.
Example input looks like this:
%(define title "mgrabmue's home")
%(define author-email "address@hidden")
<html>
<head>
<title>
%title
</title>
<body>
<h2>%title </h2>
</body>
<address>%author-email </address>
</html>
Have fun,

; This fine tool can be used to preprocess text files (I mainly use it
; to generate web pages. Usage is simple. Just pass the name of the
; file to preprocess on the commandline and the processed output will
; be written to stdout. If no file name is given, standard input is
; used to read the data.
;
; Syntax of the source files:
; ===========================
;
; Normal text in source files are simply written to standard output.
;
; Preprocessing is triggered by using the character `%' in the input
; file. The Scheme expression immediately following this character is
; read and evaluated, the result of evaluation is then written to
; standard output, if it is a string, otherwise it is only evaluated
; for side effects.
;
; Note that any whitespace following a Scheme expression is discarded
; and thus does not appear in the output.
;
; See the example source file `boo.scmtml' for how to use this script.
;;; File handling ====================================================
;; Process all expressions available on port IN-PORT.
